Video playback tends to freeze after some skipping via arrow keys, FF 57 #617

Browser Name: Firefox 57.0 Operating System: Windows 10 Software Type: Add-On Software Version: 1.9.4 Problem: After updating to Firefox 57, i noticed that with Youtube Plus loaded, the video tends to stop with a white "loading circle" in the middle, whenever i skip through the video with the right or left arrow key. For example, i hold right arrow for a second, the video stops playing (image freezes), the white circle appears, and it just keeps buffering. When i skip further, in an attempt to get it playing again, sometimes the audio will resume, but the video will go black. Why do i think this is a Youtube Plus issue? Simple, i can't reproduce it with the add-on disabled. With Youtube Plus active, it takes me maybe 10, 15 seconds of some arrow-key skipping forwards and/or backwards to provoke the problem.

Steps to reproduce: Arrow-key skipping, either keeping the right/left arrow key pressed for a while, or fast tapping of the key to skip 5 seconds at a time.

This might be a conflict with something else on top of YT+, please follow the troubleshooting guide as requested to rule out this possibility: https://github.com/ParticleCore/Particle/wiki/Report-a-problem#troubleshooting

I disabled all other add-ons, but the problem still occurs. With a new Firefox profile, i could only trigger it once so far.

A rapid succession of forward- or backward-skip commands does it. I use the shortest "Repeat delay" in the Win10 keyboard properties (slider all the way to the right). When i use the default setting (one notch away from the right), it takes longer to trigger it, but i eventually manage to trigger it there as well, when i hold the right and then the left arrow key long enough back and forth.

Other changes of note to FF: layout.css.devPixelsPerPx to "1", Youtube page zoom to 110%. Windows 10 is set to 125% (i use a 32" 2560x1440 monitor that otherwise has too high of a DPI for me). I don't know if that is a contributing factor, but i've looked at my changed parameters in about:config for a good while, and i can't figure out what could cause this.

Saturday i'm on another PC, i'll try to get to the bottom of this somehow...
